JCMAThe Japanese Electric Wire & Cable Makers' Association

Who said we're a wireless world?
Without cables, where would you get data for your smartphone ortablet? It isn't just magic.
What about your refrigerator, your air conditioner, or your TV?
Cars. Trains. Airplanes.

Electric wires and cables are the only true
link between us and the modern world.
No, we're still a very much wired world.
(thank goodness)About JCMAThe Japanese Electric Wire and Cable Makers’ Association (JCMA), founded in 1948,
brings together Japan’s electric wire and cable manufacturers.

Objectives of JCMA
Role of JCMA
Infrastructure in the form of electric power supply grids and telecommunications networks is essential tomodern life.
The electric wires and cables that underpin this infrastructure are as important to today’s society as nerves
and blood vessels are to the body.
JCMA’s social contribution comes through fostering the development of the electric wire and cable industry
on which our society depends.

JCMA formulates all types of standards for safe use of electric wire and cable.
Misuse of electric wires cause accidents and injuries every day.
We help ensure public safety by promoting standards in wire and cable design and use.
JCMA researches wire and cable performance to discern the needs of society and set standards.
It's a job we do, because many manufacturers cannot do it on their own.

Working in the electric wire and cable industry, JCMA helps
protect the global environment.
Through appropriate design, electric wire and cable can curb electricity wastage andreduce greenhouse gas emissions.
Improving manufacturing processes with high electric power and heat consumption
and increasing the efficiency of transport are other ways in which electric wire andcable can reduce greenhouse gas emissions.
To protect the global environment and make a low-carbon, recycling-oriented society
possible, JCMA is driving improvements in all forms of industrial activities using
electric wire and cable.

Superconducting
Cable

JCMA is driving globalization of Japan’s electric wire andcable industry.
Electric wire and cable manufactured in Japan is directly and indirectly exported tocountries around the world.
To enable worldwide use of Japanese wire and cable products
meeting international standards of quality, reliability and safety,
JCMA researches overseas market trends and is driving
comprehensive harmonization of Japanese and international
technical standards.

1Electric Wire and Cable Types and Applications
There are a huge number of types of wire and cable such as the cables which carryelectric power from generating plants to consumers, telecommunications wires fortelephone, Internet and other data, power supply wiring within homes and otherbuildings, and power cords for domestic appliances.
Their size, depending on their application, can range from as thick as a log to finer
than a hair.

Elevator Cable

Electricity line
Communication (Voice, data) line

Underground power distribution line

[ For electric power ]Electric power cables, called “transmission lines”, carry electricity from generating
plants to consumers.
Most transmission lines are supported on high steel pylons, but underground or
underwater cables are used in urban areas and places where pylons are difficult toconstruct.

Power cables[ For transport ]Electric wire and cable using designs and materials with high resistance to temperature changes,
shock and vibration, water, oil etc. is utilized in cars, airplanes, ships and other vehicles.
The “wire harness” commonly used in vehicles consists of different types of electric wires and cables
which have gone through cutting, binding and connector crimping processes as required by thefinished product’s specifications.

JCMA Activities
Standardization activities
To enable wire and cable users to choose the appropriate products for their application, we arestandardizing product specifications, performance, evaluation methods and handling procedures.
• Establishment and regular revision of JIS (Japanese Industrial Standards) related to wires andcables• Establishment and revision of harmonized JIS with international standards (includingconsideration of technical standards for electrical appliances and equipment)• Deliberations regarding the establishment and revision of IEC (international ElectrotechnicalCommission) standards related to wires and cables• Establishment and periodic revision of JCS (Japanese Cable Makers’ Association Standard) asa standard that complements JIS (In addition to product standards, material standards, testingand inspection standards, and technical calculation standards for wires and cables, JCS also
includes electric wire-related products such as drums for wrapping wires and cables)

Technical studies
Our studies deal with common technical issues faced by many wire and cable manufacturers andconsumer groups, such as improving the quality, reliability, and safety of wires and cables, andresponding to the latest chemical regulations. We are disseminating this information.
• Maintaining a high level of basic technology through publication and revision of technicaldocuments• Maintaining a high level of know-how through publication and revision of internal documents• Sharing regulatory information on chemical substances through RoHS Directive and ECHA(European Chemicals Agency) information• Understanding political and environmental circumstances and technology trends overseas(including technical meetings with Europacable)

Industry research
To provide the information that will contribute to the development of Japan’s electric wire and cableindustry, we conduct statistical analyses of industry trends and research various factors which may
affect the industry.
•Demand forecasting for electric wire, cable and optical fiber cable•Study and research on forecasting methods•Intelligence on manufacturers’ activities in overseas markets, collection and publication ofexport and import customs data
•Provision of statistical data to relevant government ministries, analysis of statistics producedby these ministries, reports
Preparationand publication of statistical data for the electric wire and cable manufacturing•industry based on members’ aggregate business results

Training and human resources development
To nurture the human resources on whom the development of Japan’s electric wire and cable industry
depends, we offer training courses in both basic and specialized knowledge for the electric wire andcable field.
•Our newly established expert committee on human resources development plays a major rolein human resources procurement and development by cooperating with training courses andother activities by the Japan Electric Cable Technology Center (JECTEC).
•In addition to human resources development, we organize seminars on the environment,safety, gender equality etc., and we run education and information campaigns for ourmembers.

■ As representatives of the electric wire and cable industry, we engage in the following public

relations activities to enhance the industry’s image.

Publications
We produce and market publications providing basic knowledge for safe and appropriate use ofelectric wire and cable, specialized technical information.

BulletinThrough our bulletin Densen Jiho (Electric Wire and Cable News ), we publicize JCMA activities andprovide valuable information to members.

Public relations and information
Through website and social media postings, and announcements in the press, we provide information
about JCMA and the electric wire and cable industry as a whole.
We also inform members about government policies, compliance with relevant laws and regulations
and other topics.
